OrgChart JSは、階層的データを縦方向に並べた構造で提示するツリーリストレイアウトを提供し、ネストされた情報を読みやすく

OrgChart JS by BALKAN App is a JavaScript library designed for creating flexible, interactive and customizable organizational charts for presenting structural data. This visual tool helps managers illustrate the roles and hierarchy of an organization, supporting a variety of features, including grouping, assistant nodes, expand/collapse, a built-in search field, and multi-format exports for example to PDF, PNG, SVG or CSV. Compatible with all modern browsers, it supports thousands of nodes without any impact on performance, and offers extensive customization, giving users a versatile and efficient tool for visualizing hierarchical data structures in web applications.

OrgChart JS includes the Tree List Layout, offering a space-efficient and readable way to represent hierarchical data by combining a tree structure with a linear list, enabling developers to display deeply nested hierarchies without the horizontal sprawl of traditional node-link diagrams. It allows nodes to be expanded and collapsed within a vertically aligned list, improving navigation and scalability while maintaining parent-child relationships, and supporting extensive nesting without compromising usability. This makes it particularly useful in scenarios with limited screen space or large datasets, where reducing visual complexity while preserving the full hierarchy is essential, such as administrative dashboards and data management interfaces.

OrgChart JS is licensed based on usage, offering single website, unlimited websites or SaaS, and OEM licenses. It is available as a perpetual license with 1 year maintenance and technical support. See our OrgChart JS licensing page for full details.

ActiveReportsJSを使って、関連性や階層的なデータを明確に表示する豊富なマスターディテールレポートを作成

ActiveReportsJS is a powerful, lightweight reporting tool designed to integrate advanced reporting capabilities into any JavaScript application. ActiveReportsJS enables developers to create, view, export, and print richly formatted reports entirely on the client side - with zero server dependencies.

In this blog post, MESCIUS Product Consultant Victor Stahlman demonstrates how to build nested data regions in ActiveReportsJS to create master-detail reports that display related data, such as customers and their orders, within a structured layout. He walks your through configuring datasets, nesting controls like Lists and Tables, and applying filters to correctly link and present hierarchical data relationships in your reports. Key topics include:

  • Growth vs. Static Data Regions
  • Understanding the Master-Detail Concept
  • Choosing the Report Type
  • Building the Report Structure

By implementing nested data regions in ActiveReportsJS, you can transform flat datasets into structured, master-detail reports that are easier to read and analyze.

Read the complete blog to get started building scalable, dynamic JavaScript reports that deliver more meaningful insights to your users.

ActiveReportsJS is licensed on an annual subscription or perpetual basis and is available as a Single Deployment License for non-commercial use, and as a Single Domain License or Unlimited Domain License for commercial and/or SaaS use. See our ActiveReportsJS licensing page for full details.

Optimajet FormEngineはリアルタイムのIDE検証とオートコンプリートを可能にし、問題を早期に検出しフォーム開発を改善可能

Optimajet FormEngine is a drag-and-drop React form builder that lets teams create, manage, and render complex web forms without writing frontend code. It allows developers and business users to visually design forms, store them as JSON, and render them at runtime. As a React JS library, it easily integrates into existing applications while giving developers full control over form logic, structure, and data flow, making it well suited for complex data collection.

Optimajet FormEngine enables JSON Schema validation for forms, allowing developers to validate form JSON directly within their IDE, identify structural issues, incorrect data types, and unsupported configurations early in the development process, and enforce a consistent, well-defined structure across all forms. By providing real-time feedback, inline error highlighting, and autocomplete suggestions, it improves accuracy and reduces the need for repeated testing cycles, helping developers work more efficiently while minimizing runtime errors and ensuring more reliable form implementations.

Optimajet FormEngine is licensed based on usage type (internal commercial use, public web/SaaS, or OEM embedding), number of domains for the visual editor, and access to additional ready-made components. Licenses are perpetual and include 6 months or 1 year of updates and support. See our Optimajet FormEngine licensing page for full details.

構造化されたツリーベースのナビゲーションを提供し、ユーザーが関連するセクションに直接ジャンプし、文書とより効率的にやり取り可能

Bookmark navigation in a PDF Viewer enables developers to expose the hierarchical bookmark structure embedded within a PDF so users can quickly jump to specific sections or pages. It typically presents bookmarks in a tree view synchronized with the document, allowing programmatic control and event handling for selection changes. This capability improves usability in applications that handle large or structured documents by reducing manual scrolling, supporting faster content discovery, and providing a more organized reading experience.

Several WinForms PDF Viewer components support bookmark navigation, including:
